SMOKING-PIPIE.

Specification forming part of Letters Patent No. 116,870. dated March21, 1865.

T0 aZZ whom, it may concern:

Be it known that I, Janns I; BAXTER, of Portland, in the county ofCumberland and State of Maine, have invented a new and ImprovedSmoking-Pipe; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference beinghad to theaccompanying drawings, forming a part of this specification, in whichFigure 1 represents a longitudinal central section of a pipe constructedaccording to my invention. Fig. 2 is a perspective view of themouthpiece of said pipe, showing its application as a cigar-holder.

Similar letters of reference indicate like parts.'

This invention consists in the arrangement of a double diaphragm in theinterior of the bowl of a tobacco-pipe in such a manner that anair-space is formed, which prevents heating of the pipe and keeps thetobacco free and dry. The space above the diaphragm communicates by asuitable channel with the smoke-channel, passing up through the centerof the stem to the mouth of the smoker, and another channel leads fromthe smokechannel in the stem down into the water-res.- ervoir, intendedto receive the saliva and the condensed poisonous oils, &c. Thisreservoir is emptied by removing a screw-plug,which is secured in itsbottom.

A represents the bowl of a pipe, made of wood or any other suitablematerial, and provided with a socket, B, to receive the stem 0.

D is a diaphragm or septum,which is fitted into the bowl, as shown inFig. 1 of the drawings. Said diaphragm is made of two cups, a I), struckup or otherwise made of sheet metal or other suitable material. Thesetwo cups are placed with their convex surfaces against each other, andthey are fastened together by a rivet, c, passing through their centers.By these means an air-space, d, is formed between said cups, whichprevents the pipe from heating and keeps the tobacco free and dry. Bythis arrangement of the double diaphragm the bowl is divided in thecompartments or chambersone to receive the tobacco and the other to forma reservoir for the saliva and the products of condensation. A channel,6, extends from the liquid-reservoir up through the socket B to meet thesmoke-channel in the stem, and through this channel descend the productsof condensation formed in the stem and the saliva which may chance tofind its way into said stem. Another oblique channel, f, extends fromthe lower part of the channel 0 up into the tobacco-bowl, and a smallhole inthe upper cup, a, forms the communication between said channeland tobacco-chamber.

In smoking a constant circulation of air is kept up through theair-space d between the two cups a b, and thereby the pipe is kept cool,and, furthermore, all saliva and products of combustion collect in thereservoir below the diaphragm, whence it can be easily removed, and itis not allowed to come in contact with the tobacco, which is thus keptin the proper condition for smoking. Ascrew-plug, '17, gives access tothe water-reservoir.

I am aware that perforated partitions have been applied in the bowls ofpipes; but I have never seen or heard of a diaphragm with an air-spacesuch as hereinbefore described.

The stem of my pipe is provided with a mouth-piece, h, which can bereadily taken off and used, if desired, as a cigar-holder in the mannershown in Fig. 2 of the drawings.

I do not propose to confine myself to any particular form ofconstruction, as my invention admits of a variety of forms.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A diaphragm or septum placed below thesmoke-passage in the bowl of a tobacco-pipe.

2. A diaphragm composed of one or more pieces of metal or other suitablematerial, so arranged in relation to each other or the inner surface ofthe pipe as to form a concavity for the retention of air or any materialwhich may have a cooling effect onthe contents of the pipe.

3. The channels 0 f, in combination with the diaphragm D in the bowl A,and with the stem 0, constructed and operating substantially as and forthe purpose described.

4. The diaphragm or septum, as described, with the plug, as described.
